PROCEEDINGS OF SOCIETIES. 
macro-gonidia contained in the same mother-cell with Splioerosira, 
which, taken together, seemed to suggest a sexual relation between 
them. Specimens of Volvox globator containing Sj>hoerosira were 
exhibited at the meeting. 
Microscopical Society of Liverpool. 
The seventh ordinary meeting of the eighth session of this Society 
was held on Friday evening, October 6, at the Eoyal Institution, 
the Kev. H. H. Higgins, M.A., President, in the chair. 
The Honorary Secretary announced an unusual number of dona- 
tions to the library and cabinet of slides, after which, in accordance 
with Eule 3, the election of President for the year 1877 was pro- 
ceeded with, the Eev. H. H. Higgins being re-elected by acclamation. 
Colonel Woodward, United States Army Medical Museum, Washing- 
ton, U.S.A. ; Professor Thomas Taylor, chief of the microscopical 
staff in the Agricultural Department, Washington, U.S.A. ; and 
W. G. Corthell, Esq., 103, Warren Avenue, Boston, U.S.A., were 
elected honorary members of the Society. 
Mr. Isaac 0. Thompson gave a short account of some of the 
eminent microscopists of the United States he had met with during 
a recent visit to that country. He described the process of micro- 
photography, adapted so successfully by Colonel Woodward, head 
of the Army Medical Department of the United States, at Washing- 
ton. By using the heliostat, from whence was thrown a fine pencil 
of sunlight through the microscope into the camera in a darkened 
room, Colonel Woodward prepares the finest enlarged micro-photo- 
graphs ever produced. He had, among other things, by this means 
clearly demonstrated that any difference between the blood of man, 
dog, guinea-pig, is microscopically indistinguishable, a fact which had 
been previously contested. Mr. Thompson spoke of the microscopical 
department at the Centennial Exhibition, stating that our well-known 
English makers, Messrs. Eoss and Co., E. J. Beck, and Crouch, were 
prominent exhibitors. The Americans were represented by Messrs. 
Zentmeyer, and M'Queen and Co. ; and though Americans are behind 
us in microscopes and apparatus generally, they are very skilful as 
working microscopists. He was glad to hand over to the Society's 
cabinet some valuable slides of double-stained vegetable sections, on 
behalf of Mr. Corthell, of Boston, the donor and mounter. Mr. Thomp- 
son also exhibited some eyeless fish he had brought from the Mammoth 
Cave in Kentucky, and concluded by expressing a belief that the 
American microscopists. Colonel Woodward and Mr. Corthell, whose 
names he had the pleasure of proposing as honorary members, would 
be a most valuable and helpful acquisition to the Society, and a means 
of co-operation in microscopical research between the two countries. 
The President, as the proposer of Professor Taylor, said he had 
known him personally for some years, and had recently seen him at 
Washington. He spoke in very high terms of his labours as a micro- 
scopist, and said many of his communications were to be found in the 
American Government reports on agriculture.
